Evidence for Evolution

Front

What is evidence for evolution?

Back

Evidence for evolution includes various types of data that support the idea that species change over time, such as fossil records, genetic similarities, and anatomical structures.

Front

What does it mean if organisms have similar embryos?

Back

Having similar embryos indicates that these organisms share a recent common ancestor.

Front

How does the fossil record support the theory of evolution?

Back

The fossil record provides evidence that organisms have changed over time, showing a progression of species and their adaptations.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, even if they have different functions.

Front

What are vestigial structures?

Back

Vestigial structures are body parts that have lost their original function through evolution, such as the hind leg bones in whales.

Front

What is the significance of structural evidence in evolution?

Back

Structural evidence, such as similar bone structures in different species, indicates evolutionary relationships and common ancestry.

Front

What is molecular evidence for evolution?

Back

Molecular evidence includes similarities in DNA and protein sequences among different species, suggesting a common ancestry.

Front

What are analogous structures?

Back

Analogous structures are body parts in different species that serve similar functions but do not share a common ancestry.

Front

What is embryological evidence for evolution?

Back

Embryological evidence shows that embryos of different species exhibit similar stages of development, indicating a common ancestor.

Front

How do genes provide evidence for evolution?

Back

Similarities in genes, such as homologous developmental genes, suggest that different species evolved from a common ancestor.
